Abstract

The present invention concerns a closure cap ( 10 ) for capping the aperture ( 28 ) of a container ( 20 ) having a neck ( 22 ) with a male thread ( 24 ), the cap ( 10 ) comprising a threaded female cylindrical section ( 16 ) for engaging the male thread ( 24 ) of the neck; said closure cap ( 10 ) comprising on its outer surface a skirt ( 12 ) comprising outwardly projecting gripping means ( 13 ). According to the invention, the gripping means ( 13 ) comprise projections ( 15 a, 15 b, 7 a, 17 b ) of at least two different kinds.

1 . A closure cap for capping the aperture of a container having a neck with a male thread, the cap comprising a threaded female cylindrical section for engaging the male thread of the neck; the closure cap comprising on its outer surface a skirt comprising an outwardly projecting gripper that comprises projections of at least two different kinds. 
     
     
         2 . A closure cap according to  claim 1  wherein the at least two kinds of projections are of distinct shape. 
     
     
         3 . A closure cap according to  claim 1  wherein the at least two kinds of projections are projecting outwardly in different directions. 
     
     
         4 . A closure cap according to  claim 1  wherein the at least two kinds of projections are of different flexibility. 
     
     
         5 . A closure cap according to  claim 1  wherein the at least two kinds of projections are, alone or by group, alternately positioned on the outer surface of the skirt. 
     
     
         6 . A closure cap according to  claim 1  wherein the at least two kinds of projections have distinct functions. 
     
     
         7 . A closure cap according to  claim 1  wherein the projections have a finned shape. 
     
     
         8 . A closure cap according to  claim 1  wherein the projections have a U shape which extremities are extending from the skirt. 
     
     
         9 . A container, comprising:
 a neck having an aperture;   a closure cap mounted on the neck for closing the aperture; and   the closure cap comprising a threaded female cylindrical section for engaging a male thread of the neck, the closure cap comprising on its outer surface a skirt comprising an outwardly projecting gripper that comprises projections of at least two different kinds.   
     
     
         10 . A mould for forming, by injection molding, a closure cap for capping the aperture of a container having a neck with a male thread, the cap comprising a threaded female cylindrical section for engaging the male thread of the neck, the closure cap comprising on its outer surface a skirt comprising an outwardly projecting gripper that comprises projections of at least two different kinds.
